Is it possible there are issues with the Ruby Tests? I am getter errors from the tester side when I run my code.

More specifically:

>=': comparison of String with 1 failed (ArgumentError) from tester'
from '

same here

I am having the exact same issue. I went to repl.it to test the code and I get the correct empty array. Did you get any response or answer? Have you since been able to pass the kata?

figured it out. wasn´t returning an integer. ***MAKE SURE YOU ARE RETURNING AN INTEGER!!!!

Thanks. I figured it out shortly after posting. It always helps to read the kata carefully.

with ruby, if I am trying to check number.is_a? Integer

I get an error that I have to require a module or class, but when I require Numeric, I get an error that it cant load the module. Any ideas?

are we supposed to be writing our own test cases? I have done two katas and keep getting unknown errors/unidentified errors. I know that the code is good.
